Hi,

I would like to know how to navigating between semantic elements (domain
elements), editparts, notation views, and figures.
I'm really lost when I need to get one of them from another one.
Thank you.

Guillaume

You can get a EditPart from a EObject with:
XXXEditPart.findEditPart(<EditPart to start>, <EObcejt>)

Thats may help you on a first step.

Hi Guillaume,

If you have an IDiagramGraphicalViewer you have another option: you can
use the findEditPartsForElement(String elementIdStr, Class
editPartClass) method. This returns a list of possible EditParts for
you. Try the following snippet:

/*
* You have to get this somehow; a couple of options:
*
* 1. Try anEditPart.getCurrentViewer()
* 2. If you're in an action / palette tool, you may have access
* to a getDiagramGraphicalViewer() method or similar.
*/
IDiagramGraphicalViewer viewer = ...

// Your semantic element
EObject elementToResolve = ...

/*
* You could also try substituting in a more specific class than
* EditPart here.
*/
List editParts =
viewer.findEditPartsForElement(
EMFCoreUtil.getProxyId(elementToResolve),
EditPart.class);

if (!editParts.isEmpty()) {
// What you do here is up to you, possibly:
EditPart resolvedEditPart = (EditPart)editParts.get(0);

// Do something with EditPart
}

Hope this helps / is correct for GMF veterans :)

Good luck,
Will
